Zinc Oxide generally represented as ZnO is an organic compound that is white in color and insoluble in water. It is a natural mineral that provides you with effective protection against UV rays. It acts as a barrier for protection of skin and is used in skin treatment, and in medical ointments. At present cosmetics, agriculture, rubber, glass, and ceramic industries are the ones where it is commonly used.
ZnO Additives for Rubber – Understand its role
The market of Zinc Oxide is generally represented by the rubber industry. It is the most commonly used compound in the rubber industry. Therefore, the indulgence of ZnO Additives for Rubber has the most important roles that you must be aware of. Given below are the roles:
The first step is to activate the entire curing system: To improve the solubility of zinc oxide zinc soap is formed with zinc oxide and stearic oxide. This compound formed together tends to produce a strong vulcanizing agent.
Improving the cross-linking density is the second step: To improve the cracking positions of the sulfur bonds Zn2++ salt is formed with sulfur-containing rubber accelerator. This is mainly done so that the vulcanization of rubber produces short cross-linking. Adding of cross-linking keys to the rubber accelerator is mainly done to increase the cross-linking density.
The final step is to improve the anti-aging properties of vulcanized rubber: With the process of vulcanization the polysulfide bond breaks which results in accelerating the cracking of the rubber, and it helps in improving the aging resistance. This also helps in improving the thermal properties of the compound.
Applications and Properties of Zinc Oxide for Rubber Industry
Applications: ZnO holds the property of vulcanization of rubber which makes it one of the most widely used compounds in the rubber industry. The additives of ZnO in rubber help to convert the natural rubber into a durable and used material. Thereby Zinc Oxide is considered to be the key ingredient as 50-60% of it is used in the rubber industry.
Properties: Here are the properties that make ZnO Additives for Rubber industry
- ZnO acts as an activator to speed up the vulcanization of rubber.
- Zinc oxide gives stabilization in latex gelation.
- It holds a high stability of heat stabilization.
- One of the best properties of Zinc Oxide is the stability of the destructive UV rays. It is best in the absorption of ultraviolet rays.
